VEHICLE-AXLE.

Specification of Letters Patent.

Patented @et. 19, 1909.

Application filed. June 25, 1908. Serial No. 440,334.

To all whom it may concern:

Be it known that 1, DAVID N. MARLER, a citizen of the United States,residing at McKinley, in the county of Lawrence and State of Missouri,have invented certain new and useful Improvements in Vehicle-Axles; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to vehicle axles and more particularly to thatclass in which the spindles of the axle are replaceable and the primaryobject of the invention is to simplify the construction of such devicesand to so construct them that the spindles may be more readily removed.I have also aimed to pro vide for the removal of the spindles withoutinjury to the wearing surface thereof such devices having beenheretofore constructed with grooves in the wear surface of the spindlesfor the reception of the lug or lugs of a spanner wrench.

A further object of the invention is to provide a device of this classin connectionwith which any of the ordinary types of spanner wrenchesmay be used.

In the accompanying drawings, Figure 1 is a side elevation of an axleconstructed in accordance with my invention, Fig. 2 is a verticallongitudinal sectional view there through, Fig. 3 is a verticaltransverse sectional view through the spindle taken directly outwardlyof the enlargement there on, and, Fig. 4:: is a detail perspective viewof one form of spanner Wrench which may be employed in fixing thespindles in place.

In the drawings, the axle proper is indicated by the numeral 10 and isformed at each end with a threaded socket 11 the purpose of which willbe presently fully explained, the axle being preferably enlarged indiameter at its ends as indicated by the numeral 12.

The spindle is indicated, in general, by the numeral 13, it being formedat its outer end with the usual reduced threaded portion 14: for theengagement thereon of the nut which holds the wheel hub upon the spindleand being formed at its inner end with a threaded stud 15 which isscrewed into the threaded socket in the end of the axle. At its saidinner end, the axle spindle is formed with an integral collar 16 anddirectly outwardly of the said collar with an enlargement 1'? which isformed with notches 18 for the engagement therein of the lugs of asuitable spanner wrench, it being understood, of course that the wrenchis to be engaged with the enlarged portion of the spindle to fix inplace or remove the spindle. These grooves or notches 18 not only form ameans for the application of a spanner, but also permit lubricant topass therethrough and oil the spindle.

In Fig. 4; of the drawings there is illustrated one form of wrench whichmay be used in connection with the spindle embodying my invention and inthe said figure, the numeral 19 denotes the handle of the wrench and thenumeral 20 the body or annulus thereof, the said body being formed withthe usual pair of lugs 21 which are to be engaged in the grooves formedin the enlarged portions of the spindle, it being understood of coursethat the annular head of the spanner wrench is to be slipped over thespindle to permit of such engagement.

It will be apparent from the drawings and from the foregoing descriptionthat the notches or other elements with which the spanner Wrench is tobe engaged are not formed upon the wear surface of the spindle and thatconsequently the spindle may be removed Without injuring the saidsurface.

What is claimed is:

The combination with an axle provided with a threaded socket, of aspindle having a threaded stud on the inner end thereof engaging saidsocket, a collar bearing against the end of'said axle, and a secondcylindrical collar outside of and in spaced relation to the firstcollar, said second collar be ing provided with a pair of oppositelydisposed grooves forming lubricant .channels and adapted to receive thelugs of a spanner.

In testimony whereof, I affix my signature, in presence of twoWitnesses.

DAVID N. MARLER.
